I don't see any update to the macio stuff... have you fixed that
separately or are you up to breaking it -again- ? :-)
You should do build tests with a pmac32 or g5 defconfig every now and
then.

I still don't like it very much.. why not chmod'ing it +x instead ? :-)

What do you mean by, "no longer works?" The driver works fine for us,
even without TMR_CTRL[TE] set. We tested the driver on two MPC8313ERDB
REV C boards, one P2020DS, and one P2020RDB.

No, we did not set TMR_CTRL[TE].
For the Rx timestamps, we simply enabled them unconditionally. The
effect of not setting TMR_CTRL[TE] was that the timestamps were
invalid, but that should not matter if user space has not configured
the PTP clock. We left the TMR_CTRL[TE] bit for the PTP clock driver
(recently submitted and discussed on netdev). Actually, I copy the PTP
clock driver to the target via 'scp' during development, and I never
had any trouble.

The BSPs that we have, for the MPC8313ERDB and the P2020RBD both
include a (hacky) PTP timestmaping driver. Can you be more specific
about where and when Freescale is disabling timestamping?

Okay, but now we want to identify what exactly works and what not. As
mentioned, we tested this driver on four different boards and did not
see any problems.

Richard

Heh, thanks but no :-)
I want to keep that code here, until we hook it up again. It was hooked
up properly in some internal stuff that didn't go upstream for some
reason and I need to fix that.

I tend to agree with Anton here.
BTW. Why not make of_device a wrapper (or even alias of)
platform_device ? :-) That way you get the resource array etc.. for free
and it will make the whole of_device vs. platform_device issue moot.

Nope :-) Though it would be nice to also remove the call sites too and

Add of_driver_match_device() helper function. This function can be used
by bus types to determine if a driver works with a device when using OF
style matching. If CONFIG_OF is unselected, then it is a nop.

Implement generic OF gpio hooks and thus make device-enabled GPIO chips
(i.e. the ones that have gpio_chip->dev specified) automatically attach
to the OpenFirmware subsystem. Which means that now we can handle I2C and
SPI GPIO chips almost* transparently.
* "Almost" because some chips still require platform data, and for these
chips OF-glue is still needed, though with this change the glue will
be much smaller.

* [PATCH v2 3/5] of/gpio: stop using device_node data pointer to find gpio_chip
From: Grant Likely @ 2010-06-10 5:40 UTC (permalink / raw)
To: dbrownell, avorontsov
Cc: bgat, dbaryshkov, devicetree-discuss, linux-kernel, akpm,
linuxppc-dev
In-Reply-To: <20100610053439.16716.53944.stgit@angua>
Currently the kernel uses the struct device_node.data pointer to resolve
a struct gpio_chip pointer from a device tree node. However, the .data
member doesn't provide any type checking and there aren't any rules
enforced on what it should be used for. There's no guarantee that the
data stored in it actually points to an gpio_chip pointer.
Instead of relying on the .data pointer, this patch modifies the code
to add a lookup function which scans through the registered gpio_chips
and returns the gpio_chip that has a pointer to the specified
device_node.

* [PATCH v2 2/5] of/gpio: Kill of_gpio_chip and add members directly to gpio_chip
From: Grant Likely @ 2010-06-10 5:40 UTC (permalink / raw)
To: dbrownell, avorontsov
Cc: bgat, dbaryshkov, devicetree-discuss, linux-kernel, akpm,
linuxppc-dev
In-Reply-To: <20100610053439.16716.53944.stgit@angua>
From: Anton Vorontsov <avorontsov@ru.mvista.com>
The OF gpio infrastructure is great for describing GPIO connections within
the device tree. However, using a GPIO binding still requires changes to
the gpio controller just to add an of_gpio structure. In most cases, the
gpio controller doesn't actually need any special support and the simple
OF gpio mapping function is more than sufficient. Additional, the current
scheme of using of_gpio_chip requires a convoluted scheme to maintain
1:1 mappings between of_gpio_chip and gpio_chip instances.
If the struct of_gpio_chip data members were moved into struct gpio_chip,
then it would simplify the processing of OF gpio bindings, and it would
make it trivial to use device tree OF connections on existing gpiolib
controller drivers.
This patch eliminates the of_gpio_chip structure and moves the relevant
fields into struct gpio_chip (conditional on CONFIG_OF_GPIO). This move
simplifies the existing code and prepares for adding automatic device tree
support to existing drivers.

* [PATCH v2 0/5] Generalize OF gpio support code
From: Grant Likely @ 2010-06-10 5:40 UTC (permalink / raw)
To: dbrownell, avorontsov
Cc: bgat, dbaryshkov, devicetree-discuss, linux-kernel, akpm,
linuxppc-dev
This series makes all gpio drivers usable from the OF support apis by
automatically registering a default OF translator when the of_node
pointer is assigned. These patches are heavily based on the work that
Anton did earlier, but I didn't add the notifiers infrastructure and
the OF data now lives directly inside the core gpio_chip structure so
that fewer gymnastics are needed to get at it.
These patches are currently sitting in the following branch:
git://git.secretlab.ca/git/linux-2.6 next-devicetree
---
Anton Vorontsov (3):
gpiolib: cosmetic improvements for error handling in gpiochip_add()
of/gpio: Kill of_gpio_chip and add members directly to gpio_chip
of/gpio: add default of_xlate function if device has a node pointer
Grant Likely (2):
of/gpio: stop using device_node data pointer to find gpio_chip
of/device: Add OF style matching helper function

Actually, you should never add someone else's signed-off-by unless
they specifically ask you to. The signed-off-by lines are supposed to
show the path that the patch took to get into the tree, so in general
only the original author(s) and the maintainers who passed the patch
along should add signed-off-by lines. It would only be a maintainer
who would add someone else's signed-off-by, and then only if someone
who needs to sign off on the patch had forgotten and then asked the
maintainer to correct their mistake.
In this case the appropriate way to give credit would be just a
sentence in the patch description; no formal tag is needed.
Paul.

I have seen it only once, but it did get my attention. I will try running
it again this evening when/if kernel-ml8 is free again. 2.6.35-rc2,
I should have mentioned.

Wow... looks like the preempt count of the idle task got busted or
something ... how reproduceable ? Something like a record of previous
interrupts might be useful..
Cheers,

* Port Linux to ML510
From: kostas padarnitsas @ 2010-06-09 23:02 UTC (permalink / raw)
To: linuxppc-dev
[-- Attachment #1.1: Type: text/plain, Size: 644 bytes --]
Hello,
I am trying to port Linux to PowerPC on the ML510 Xilinx board. I am using EDK 10.1.3 to build the hardware and also device tree generator and the linux kernel from xilinx git. I followed the tutorial from http://xilinx.wikidot.com/powerpc-linux but I have no output. I have attached my .mhs file and the .dts. Any ideas what may cause this problem because I did the same thing with ML507 and it was working perfectly?
Thanks in advance,Kostas

* [PATCH] gianfar: Revive the driver for eTSEC devices (disable timestamping)
From: Anton Vorontsov @ 2010-06-09 19:32 UTC (permalink / raw)
To: David Miller; +Cc: netdev, Manfred Rudigier, linuxppc-dev
Since commit cc772ab7cdcaa24d1fae332d92a1602788644f7a ("gianfar: Add
hardware RX timestamping support"), the driver no longer works on
at least MPC8313ERDB and MPC8568EMDS boards (and possibly much more
boards as well).
That's how MPC8313 Reference Manual describes RCTRL_TS_ENABLE bit:
Timestamp incoming packets as padding bytes. PAL field is set
to 8 if the PAL field is programmed to less than 8. Must be set
to zero if TMR_CTRL[TE]=0.
I see that the commit above sets this bit, but it doesn't handle
TMR_CTRL. Manfred probably had this bit set by the firmware for
his boards. But obviously this isn't true for all boards in the
wild.
Also, I recall that Freescale BSPs were explicitly disabling the
timestamping because of a performance drop.
For now, the best way to deal with this is just disable the
timestamping, and later we can discuss proper device tree bindings
and implement enabling this feature via some property.

Makes sense to me. There might be advantages to be able to track the
size of the "stack allocation" even for other architectures, too.

I agree its easier and would avoid #ifdefs in the applications.
Peter, Arnd, Roland - do you have any concerns with requiring all
architectures to specify the stack to eclone() as [base, offset]
To recap, currently we have
struct clone_args {
u64 clone_flags_high;
/*
* Architectures can use child_stack for either the stack pointer or
* the base of of stack. If child_stack is used as the stack pointer,
* child_stack_size must be 0. Otherwise child_stack_size must be
* set to size of allocated stack.
*/
u64 child_stack;
u64 child_stack_size;
u64 parent_tid_ptr;
u64 child_tid_ptr;
u32 nr_pids;
u32 reserved0;
};
sys_eclone(u32 flags_low, struct clone_args * __user cargs, int cargs_size,
pid_t * __user pids)
Most architecutres would specify the stack pointer in ->child_stack and
ignore the ->child_stack_size.
IA64 specifies the *stack-base* in ->child_stack and the stack size in
->child_stack_size.
Albert and Randy point out that this would require #ifdefs in the
application code that intends to be portable across say IA64 and x86.
Can we instead have all architectures specify [base, size] ?
Thanks

* [PATCH 2/2 v2] sound/soc: mpc5200_psc_ac97: Use gpio pins for cold reset.
From: Eric Millbrandt @ 2010-06-09 15:54 UTC (permalink / raw)
To: Grant Likely; +Cc: Mark Brown, linuxppc-dev, Eric Millbrandt
The implementation of the ac97 "cold" reset is flawed. If the sync and
output lines are high when reset is asserted the attached ac97 device
may go into test mode. Avoid this by reconfiguring the psc to gpio mode
and generating the reset manually.
>From MPC5200B User's Manual:
"Some AC97 devices goes to a test mode, if the Sync line is high
during the Res line is low (reset phase). To avoid this behavior the
Sync line must be also forced to zero during the reset phase. To do
that, the pin muxing should switch to GPIO mode and the GPIO control
register should be used to control the output lines."

- Amended with comments from Mark Brown
- Fall back to the original reset implementation if no gpio pins are define=
